Longfin Svetovidov's char
Salvethymus svetovidovi
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Longfin Svetovidov's char faces severe pressure from habitat degradation in its restricted range within the Elgygytgyn crater lake system in Chukotka, Russia. Climate change poses a significant threat through warming water temperatures that could disrupt the species' cold-water adaptations and alter the lake's thermal stratification. The species' extremely limited distribution makes it particularly vulnerable to any environmental changes or human disturbances in this single location.
Habitat
This endemic char inhabits the deep, cold waters of Lake Elgygytgyn, a meteorite crater lake in the remote Chukotka region of northeastern Russia. The species is adapted to the lake's unique oligotrophic conditions and stable cold-water environment at depths typically exceeding 50 meters.
